Seres developed an in-car toilet design that allows the system to fit inside an electric vehicle without taking up additional room. Engineers put the entire assembly on a movable rail connecting to the seat frame. When it is not needed, the toilet simply disappears beneath the floor. All it takes is a simple nudge or a whispered order, and it appears like a drawer.
Voice commands activate the system with a simple phrase that initiates the toilet function. Once you get access to it, the rest of the interior remains largely unchanged. A built-in fan draws in air and expels foul air through an exhaust pipe. Pee and other waste enter a tank, which must be manually emptied when you get at your destination. They include a small heating element inside that helps to dry everything up, making cleanup easier.

The beauty of it is that when it’s not in use, nothing sticks out, allowing you to use the space for seating or storage. The patent filing cites extended journeys, camping vacations, and any time spent living in your car as the primary reasons for this functionality. Traffic delays that used to force you to make painful decisions are no longer as inconvenient. Seres already manufactures automobiles with features meant to make your daily commute easier. They compete in a market where each new model strives to be unique. This invention fits nicely into that approach by figuring out how to transform something you use every day into another part of the car.

There are still several technicalities to be sorted out before anyone can install this system in a real car. There is concern that scents may remain if the fan or seals fail to function properly when the unit is frequently utilized. Emptying the tank is also a bother, whether at the gas station or at home. If you’re sharing a car with a group of people, you might be afraid to take turns in such a small place, and there’s also the question of how well it will withstand all of the road’s bumps.
Seres hasn’t said whether they intend to manufacture any automobiles with this system in them. Patents don’t always come to fruition, therefore there’s a high risk this idea will go unnoticed. Nonetheless, it’s a creative solution to a problem that almost every driver has encountered at some point. If it ever gets it out of the design phase, road vacations may not be such a burden.
